My son tried to solve a Rubik’s cube at the childminder, showing off since he does it routinely at home, but he got stuck. This is a plea for help!
We learned from the Think Maths instructions. At step 4 where the bottom ought to be a cross, dot, line or V, he says it did this - both line and V without being a cross. Then doing either the L move or the V move didn’t find a cross. I don’t know how to replicate the problem, so set up the yellow layer starting in this position (but without the first two layers solved). Playing around, we found we appeared to be stuck in a loop - depending on orientation we could sometimes rotate the line 90 or swap to a dot and back. I wasn’t able to inspect the childminder’s cube but he says the rest of the cube was two complete layers as it should be. Is this a situation that arises? What do you do if it does?
